As shown in Figure 1, the device of realizing video telephone comprises connected module and the control module of arranging; Also comprise the synthesis module, video module, the audio-frequency module that are connected with described control module; Video module is all connected with synthesis module with audio-frequency module.
Module is set, for different videophone mode is set;
Control module, for being used selected videophone mode to carry out video call; When videophone mode refers to video mode, use selected video mode to control the output of video module to video data; When videophone mode refers to audio mode, use selected audio mode to control the output of audio-frequency module to voice data; When videophone mode refers to the set of video mode and audio mode, use selected video mode to control the output of video module to video data, use selected audio mode to control the output of audio-frequency module to voice data, different videophone mode refers to video mode and in audio mode, to have a pattern at least different.
Video mode is normal video pattern or default video mode, the value that different default video modes refer to the video image parameter of use while carrying out video call is different, and video image parameter comprises one or more in following parameter: the mosaic degree of the jitter amplitude of picture brightness parameter, picture contrast, picture dimension, picture, the refresh rate of picture, picture.Audio mode is normal audio pattern or default audio mode, and different default audio modes refer to and while carrying out video call, use different audio files sound as a setting.
Control module, while also carrying out video call for user under selected videophone mode, need to switch to and under other videophone mode, continue described video call according to call.
Video module, for referring to video mode or referring to video mode and during the set of audio mode, export corresponding video data according to the processing of control module in videophone mode; When videophone mode refers to audio mode, actual video data in output process of video call.
Audio-frequency module, for when videophone mode refers to video mode, actual video data in output process of video call; In videophone mode, refer to audio mode or refer to video mode and during the set of audio mode, according to the processing of described control module, export corresponding voice data.
Synthesis module, for output after the voice data of the video data of video module output and audio-frequency module output is synthesized.
As shown in Figure 2, the method that realizes video telephone comprises following content:
Step 201, pre-defined different videophone mode;
Step 202, when user transfers to video telephone or answers video telephone, is used selected videophone mode to converse.
Videophone mode refers to video mode, and video mode is normal video pattern or default video mode, and normal video pattern is to point to opposite end directly to transmit the video data that the camera collection of communication terminal arrives, and the video data collecting is not done to any processing.The value that different default video modes refer to the video image parameter of use while carrying out video call is different, and described video image parameter comprises one or more in following parameter: the mosaic degree of the jitter amplitude of picture brightness parameter, picture contrast, picture dimension, picture, the refresh rate of picture, picture.
Videophone mode refers to audio mode, and audio mode is normal audio pattern or default audio mode.Normal audio pattern is to point to opposite end directly to transmit the voice data that the radio equipment of communication terminal collects.Different default audio modes refer to and while carrying out video call, use different audio files sound as a setting.Audio file also can import or record generation by user, audio file can embody the audio under different scenes, for example room, bathroom, parlor, stone chamber, auditorium, music hall, airport, railway station, lane, forest, business district, street, food market, parking lot, sewer etc. scene.
Videophone mode can also refer to the set of video mode and audio mode, and different videophone mode refers to video mode and in audio mode, to have a pattern at least different.
The combination of these audio modes and video mode is freely selected to determine by user, as the call mode of video telephone.In the time of these pattern usings, should not fix, for example, the quality of picture, can be from preferably adjusting to the poorest in the process of call, but from the angle of probability, guarantee that the speech quality most of the time is in worst state, with the environment that guarantees user place by the other side's identification not out, can make again the other side not think that user does not want surrounding environment to show the other side to see simultaneously.
In said method, user can also be switched videophone mode in carrying out process of video call, selects other videophone mode to continue described call.When user carries out video call under pre-setting video or audio mode, can also revert to normal mode.
Device of the present invention, can be applicable to all kinds terminal, conveniently realizes the complex functionality of a plurality of video source.Telecom operators only need that user terminal software is carried out to suitable modification (increasing corresponding service software module) and can meet the demands.The present invention can be widely used in various terminal equipments, such as mobile phone, landline telephone etc.Method of the present invention, makes full use of the simplicity of user terminal software upgrading and is easy to the property transformed, and only needs user terminal software suitably to change, and just can make a plurality of video source realize synthetic function.
The present invention can effectively protect user's privacy in calling course of video telephone, and user can select normal talking or default audio frequency and video pattern as required, reaches different visual effects.In addition, can also improve the recreational of mobile terminal.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
